An  Extension 

of   the 

Dewey   System   or    Classmcation 

Applied    to 

Metallurgy,  Metallograpny  ana  Assaying

The  rapid  growth  of  metallurgical  industries  has  rendered 
necessary  a  more  complete  system  of  classification  of  the  literature 
on  this  subject  than  is  afforded  by  the  Dewey  classification.  The 
most  complete  extension,  covering  all  engineering  as  well  as  metal- 
lurgical subjects,  is  found  in  Bulletin  ISTo.  9,  issued  in  ISTovember, 
1906,  by  the  Engineering  Experiment  Station  of  the  University  of 
Illinois.  In  this  bulletin  the  extensions  relating  to  mechanical, 
electrical,  and  railway  engineeriug  are  complete,  but  the  other 
branches  are  incomplete.  The  extension  herein  given  has  been 
prepared  to  cover  this  deficiency  in  metallurgy,  metallography,  and 
assaying.

In  the  Dewey  decimal  system  the  entire  field  of  knowledge  is 
divided  into  ten  main  classes,  nnmbered  l)y  the  digits  from  0  to  9. 
The  primary  classes  are

History. 

Each  of  these  classes  is  similarly  divided  into  ten  divisions. 
The  divisions  are  divided  into  ten  sections,  and  the  process  is  re- 
peated as  often  as  is  necessary.  Thus  669  means  Class  6  (Useful 
Arts),  Division  6  (Chemical  Technology),  and  Section  9  (Metal- 
lurgy). In  carrying  the  system  out,  a  decimal  point  is  ]ihiced  for 
convenience  after  every  third  digit.  To  illustrate  further,  con- 
sider 669.145.412  (Bessemer  Converter  Tuyeres)  ;  669  as  already 
explained  means  Metallurgy;  669.1,  the  Metallurgy  of  Iron  and 
Steel;  669.14,  the  Manufacture  of  Steel;  669.145,  the  Bessemer 
Process  for  Steel  Manufacture;  669.145.4,  the  Bessemer  Con- 
verter; and  669.145.41,  the  Construction  of  the  Bessemer  Con- 
verter; and  669.145.412,  Bessemer  Converter  Tuyeres. 

The  table  of  numbers  is  followed  by  a  relative  index  in 
which  each  table  title  is  arranged  alphabetically  with  its  ]:)roper 
number.  It  is  clearly  impossible  to  include  all  the  terms  con- 
nected with  metallurgy,  metallngraphy,  and  assaying  in  this  index, 
but  enough  are  given  to  enable  the  user  to  assign  the  pro]ioi'  num- 
ber to  almost  any  subject  that  may  arise.  The  relative  index  is 
very  useful  to  the  person  in  search  of  information  indexed  l)y  this 
system,  in  that  it  shows  at  once  the  various  numbers  under  wliieh 
an  item  occurs  in  cnse  it  has  more  than  one  number.  For  exam- 
ple: roasting  of  arsenical  ores  ii  jdaccMl  under  669.22.  un(h'r 
669.32,  and  under  669.42. 


THE  COLORADO  SCHOOL  OF  MINES.  5 

In  the  present  extension  of  the  system  the  main  subdivisions 
under  669  have  been  left  unchanged  with  the  exceptions,  that  use 
is  made  of  the  digit  (0),  by  making  669.0,  General  Metallurgy, 
which  includes  fuels,  furnaces,  and  refractories,  and  that  under 
669.8  is  placed  metallography,  a  branch  of  metallurgy  which  is 
growing  rapidly  and  is  so  closely  allied  to  it  that  it  should  be 
classed  near  metallurgy.  These  changes  are  thought  advisable,  as 
669  (Metallurgy)  has  not  been  sufficiently  extended  to  cause  con- 
fusion. The  character  (0)  has  been  used  throughout  this  classifi- 
cation as  any  other  digit,  for,  although  after  a  decimal  point,  it 
does  not  increase  the  number  numerically,  yet  it  acts  as  a  distinct- 
ive symbol.  All  items  pertaining  to  ore  dressing,  except  in  a  gen- 
eral way,  are  excluded,  as  ore  dressing  is  classed  under  622  (Min- 
ing). The  general  forms  of  the  Dewey  classification  have  been 
modified  to  suit  the  subject,  and  where  it  seems  desirable  they  are 
stated  in  full.  An  elaborate  system  of  cross  reference  does  not 
seem  necessary,  as  the  relative  index  shows  where  an  item  should 
be  placed. 

For  a  person  keeping  an  index  on  the  subjects  of  metallurgy, 
metallography,  and  assaying,  and  not  too  many  other  subjects,  it  is 
convenient  to  substitute  a  letter  for  the  first  three  digits,  thus  for 
669  (metallurgy,  metallogTaphy,  and  assaying)  the  letter  M.  In 
making  small  subdivisions  it  is  sometimes  convenient  to  arrange 
the  subjects  in  alphabetical  order,  giving  a  combination  of  the 
decimal  with  the  alphabetical  system.  For  the  benefit  of  persons 
who  wish  to  extend  the  system  for  their  own  use,  blank  spaces 
have  been  left  where  it  seems  advisable. 

The  decimal  system  of  classification  is  adapted  to  the  index- 
ing of  books,  notes,  clippings  from  journals,  drawings  and  cata- 
logues. In  libraries,  books  and  pamphlets  may  be  filed  according 
to  the  system  with  an  alphabetical  card  index  showing  under  what 
numbed  the  book  sought  is  to  he  found.  In  indexing  current  tech- 
nical literature,  where  the  number  of  cards  becomes  large,  it  will 
be  found  convenient  to  keep  the  card  index  in  order  of  the  num- 
bers of  the  decimal  system  rather  than  by  alphabetical  order. 

Engineers  can  use  the  system  in  three  ways:     first,  to  keep 


THE  COLORADO  HCHOOL  OF  MINES. 


a  card  index  of  technical  literature;  second,  to  file  clippings  from 
journals,  notes,  drawings  and  catalogues,  without  a  card  index ;  or, 
third,  for  a  combination  of  the  card  index  with  the  filing  system, 
so  that  a  reference  to  a  journal  of  which  there  is  no  clipping  at 
hand  can  be  recorded  with  other  references. 

In  filing  clippings,  an  envelope,  7%  inches  long  and  514 
inches  wide,  is  a  convenient  size.  The  spacing  for  recording  may 
be  arranged  as  indicated  on  the  type  form  given  below.  Articles 
under  a  sub'livision  may  he  filed  in  alphabetical  order.

The  index  card  refers  to  an  aiticle  which  appeared  in  Metal- 
lurgical and  Chemical  Engineering,  Vol.  9,  page  127,  March, 
1911,  and  occupies  three  pages,  with  no  illustrations.  The  class 
number  669.147  serves  to  locate  the  card  in  the  case  of  the  index. 

The  decimal  system  possesses  several  very  important  advan- 
tages over  the  alphabetical  system :  lirst,  it  groups  allied  sub- 
jects which,  under  the  alphabetical  arrangement,  would  be  widely 
scattered ;  second,  under  the  alphabetical  system  there  are  many 
cases  in  which  it  is  difficult  to  determine  wdiat  letter  to  assign  to  a 
subject,  and  much  confusion  results,  all  of  which  is  avoided  in  the 
decimal  system ;  and  third,  in  the  decimal  system  there  is  great 
flexibilitv  and  room  for  extension.
